PAUL xnmsxr, or BERLIN-PANKOW, GERMANY, ASSIGNOR TO smmmvs & HALsxE GUN-LAYING APPARATUS.

Application filed October 26, 1923. Serial No. 670,884.

To all whom it may concern:

vBe it known that I, 'PAUL KAMINsKI, a citizen'of the German Empire, residing at Berlin-Pankow, Germany, have invented certain new and useful Improvements in Gun- Laying Apparatus, of which the following is a specification. This'invention relates to gun laying apparatus and more articularl to apparatus I for adjusting the e levation 0 several pieces of ordnance simultaneously from an observation point by means of remote electric control.

In the known remote controlling devices for guns all guns of a battery receive as a rule the same range communicated from the transmitter at the central station or from the directing-gun. Owing to the varying distance, of the guns from the range transmitter or from the directing-gunvthe impact of the projectiles thus varies in' correspondence -with these varying distances; To correct this error special correction tables or conversion apparatus were employed at each in- '2 dividual gun. This proceeding caused loss .of time and mistakes.

The object of the present invention is to avoid these drawbacks and to eliminate the human factor by combining an automatic correcting device with each gun or with the range transmitting apparatus.

In the drawings: Fig. 1 is a diagram of the principle underlying the invention. 3 Fig. 2 is the application of the improved apparatus to the elevating device of the gun. Fig. 3 is the application of the improved apparatus to the tangent sight of the gun and Fig. 4. on the directing telescope of the gun. Similar parts are indicated by the same reference signs throughout all the figures of the drawings.

The principle of the invention will first be pointed out by reference to Fig. 1. Along the base-line 0-180 are disposed the pieces of ordnance IIV and the transmitter G. The target is assumed to be at 60. The distances of the target from the guns and the transmitter are indicated by with the corresponding index, the angles between the line from the directing gun to target and the base-line, the so-called lateral direction position, is indicated by a and the corresponding index and the distances of the guns from the transmitter by a. and the'cor respondlng index. As the distance of the guns from one another is very small compared with the distance of the target, it may be assumed that E zE -l-a, cos a At oz:0 or 180 E =E ia,-, at oz=90 E, may be made E with sufiicientaccuracy.

It is therefore required to correct the linear value a multiplied by the cosine of the lateral direction a.

In the Figures 2-4 various devices are shown, which effect this correction auto matioally.

Referring to Fig, 2, which shows the improvement applied to the elevating apparatus of the gun, the pointers 2/ and 2 of the coarse and fine receivers of the receiver plant B are electrically controlled from. a directing telescope. The gun is elevated in likewise known manner by means of the crankhandle H across s. 8 t and the levelling quadrant L and simultaneously the counter pointers z, and .2 are by the gearing 0 3 to 9 made to follow the remotely controlled pointers .2 and 2 During this rotation the drum is furnished with a spiral groove is rotated by the wheels 11, 12, 13, 14. The drum In acts as so-call'ed' sine link. It is journaled in a rotatable bow b, which is operated by the lateral direction levelling wheel H across 19 in correspondence with the lateral angle a, The spiral groove in the drum k is gauged in accordance with the angle of elevation corresponding with the distance. Preferably similar drums are employed for all guns and the "arying distance of the guns is provided for by different; ratios of transmission, for instance in the/Z115- wheels 16, 17. The groove of the drum la is engaged by a pin 'n. The pin a slides along a spindle 0, which is journaled in therotatable bow b. The pin a engages withlts I other end a slot 1 of a link, onebeam st 1 of which is provided with a rack. This link is so arranged within the casing of the apparatus, that it can only slide in the directlon of the beam provided with the rack. By this rack the motion is transmitted to the planet wheel 7 across the wheels 15, 16, 17, 18 and thereby to the counter pointers z, and 2 Referring to Fig. 3 which'shows the lmproved apparatus applied to the tangentsight of the gun and not to the gun itself, it Will be seen, that the counter pointers .2 and 2 are made to follow the remotely controlled pointers 2 and .2 of the receiver plant across the intermediate members 3-9 by turning the tangent-sight adjusting wheel H The wheel H moves simultaneously across 8 the toothed quadrant L of the telescope support F. Across the intermediate members 11-14 the drum 7c is rotated again, which in its turn acts again upon the planet wheel 7 by means of the parts n, st, 15 to 18. Thelateral direction adjusted by the handwheel H across 20, 21, 22 is transmitted by the toothed rim 23, pinion 24, articulated shaft 25 and gearing 19 to the bow b.

Preferably the correcting members for the constructions illustrated in Figs. 2 and 3 are housed within the receiver casing. The drum is is adapted to be easily exchanged in accordance with the various charges of the gun (for instance fight-practice-aiming charge).

Fig. 4 shows a diagrammatic representation of the application of the correcting device at the transmitter, so that'the guns receive right away the range corrected in accordance with their position. By means of the crank-handle 30, which may be replaced by any suitable power drive, the transmitter distance is adjusted upon the scale 31. Hereby the common to all guns is adjusted across the elements 32, 33 and 34:. shaft 33 revolves across 35, 36 the planet wheels 37 of the fine transmitters F --F belonging to each individual gun. When adjusting the crank 30 the drum is is turned by the parts 11, 12, 13 and 14, which transmits its motion across n, st, 15, 40, 16, 17, 18 and planet wheel 37 to the fine transmitting system F F The blow is in this construction rotated by the adjustment of the lateral direction upon the scale 38 by means of the crank 39 across the worm gear 4O.

The lateral direction may, however, also be taken directly from the directing telescope of the transmitter plant. The different distance of the guns is preferably provided for by the ratio of transmission of the wheels 17.

It will be readily understood that the invention is by no means limited to the illustrated subdivision for coarse and fine systems and the follow-pointer plant may equally well be replaced by direct remote control.
